HTTP/2 enable does not work

Question

On Ubuntu 14.04.4 LTS with HHVM(HipHop VM 3.14.1) and Nginx(nginx/1.10.1)

I try to enable HTTP/2 like the following in my vhost

server {
    listen 443 ssl http2 default_server;
    listen [::]:443 ssl http2 default_server;

    root /var/www/mydomain;
    index index.html index.htm index.php;

    server_name mydomain.com;

    ssl_certificate /etc/nginx/ssl/www_mydomain_com.pem;
    ssl_certificate_key /etc/nginx/ssl/server.key;

    access_log /var/log/nginx/localhost.laravel-access.log;
    error_log  /var/log/nginx/locahost.laravel-error.log error;

    charset utf-8;

    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }

    location = /favicon.ico { log_not_found off; access_log off; }
    location = /robots.txt  { log_not_found off; access_log off; }

    error_page 404 /index.php;

    include hhvm.conf;  # The HHVM Magic Here

    # Deny .htaccess file access
    location ~ /\.ht {
        deny all;
    }

    #Add Expires headers
    location ~* \.(?:ico|css|js|gif|jpe?g|png|jpg|woff|woff2)$ {
        expires 30d;
        add_header Pragma public;
        add_header Cache-Control "public";
    }
}

server {
    listen         80;
    listen    [::]:80;
    server_name    mydomain.com;
    return         301 https://$server_name$request_uri;
}

But, when I try to check at HTTP/2 test, I always get

Negative! mydomain.com does not support HTTP/2.0. Supported protocols: http/1.1

ALPN is not supported.

Edit

$ nginx -V as the following

How I can enable HTTP/2?

That's the output of `nginx -v`, but I asked for the output of `nginx -V`. — gxx, Jun 27 '16 at 07:37

Well, the error message you've got is quite obvious:

ALPN is not supported.

Application-Layer Protocol Negotiation aka ALPN is a Transport Layer Security (TLS) extension for application layer protocol negotiation. ALPN allows the application layer to negotiate which protocol should be performed over a secure connection in a manner which avoids additional round trips and which is independent of the application layer protocols. It is used by HTTP/2. Additionally, it's also needed by HTTP/2 (AFAIK).

ALPN is supported by / using openssl => 1.0.2. According to your output of nginx -V, your nginx was built with òpenssl 1.0.1f, so this can't and won't work. To enable (and use) HTTP/2, you've to run a more modern version of nginx. Recently, I've explained a way to do this here. (But please don't copy/paste this, this won't work, as it deals with Debian.)
